Rize 2 Carbon questions...

I just bought a Rize 2 Carbon for a very good price. It is new, just been sitting in the store for a couple of years. I have a couple of questions if anyone can answer...

To set the sag on the Lefty 130 Max Fox Carbon, am I right in thinking you have to strip the top end down to tighten or release the spring inside? Any tips on doing this?

Has anyone had experience traveling with one of these? Any suggestions as to transport bags and the Lefty/stem/bar situation to enable it to fit into a regular case? Or is there some case someone has found that does the job well?
